Xperia Z3- How Do I Downgrade to KitKat 23.0.A.2.98 So I can Get Root?

Could not downgrade to get root
Hi all,
I'm a very big fan of this community, but only to read and learn. But now I need your help...
History: rooted my phone few months ago in the way told in this post. Everything went well, but last week my screen broke. Sony fixed it but also put latest software on it... and removed root.
Today I tried to downgrade to KitKat 23.0.A.2.98 again (stil had the FTF) to get root again, so I can put back my Nandroid backup. I didn't manage to get it working... after restarting after flashing when the blue screen appears before you are asked to unlock your SIM... my phone makes a pitching noise for 10 seconds and then reboots again. The process repeats itself again and again.
Fortunately I can flash the latest firmware back and my phone works again... thank God because a thought for a moment I soft bricked my phone.
Anyone a solution to get root? I'm now on LP 5.1.1
thnx!!!!
ciao

How did you downgrade? The normal way... means: using flashtool (latest version) and which settings did you use for flashing? ...and did you try downloading a different version and flashing it?

Hi Tom, yes I did it the normal way... latest flashtool and settings the same as before, so I checked no boxes. After that didnýtwork I tried something different, so checked all wipe options. I also tried a different version and flashed that via the normal way. That didn't work either... the only flash that worked so far was 23.4.A.0.546 / R7C. But that's way to new to get root via downgrading

So the flashing process did always work without problems? But the result is always as you described?
And if it's only about root... did you try Kingroot? Afaik it is supposed to work on almost all versions.
Another thing: I don't remember all options by heart (and can't check them atm)... but maybe try some of the provided options.

It's more that when I reboot after having flashed back to earlier FW my phone bootloops... so I don't even get a chance to continue and root. Very annoying!
My next move is to find another old stock FTF (probably not a Dutch one) and will try to flash that one with different boxes checked.

When I'm back home I can check for the one that I used (quite recently) when relocking BL and rooting etc. If I don't find the source anymore, I can maybe upload it for you.

Ok... so this was the version that I used... to downgrade and root:
D5803_23.0.A.2.93_Generic_GLOBAL_1286-9917.ftf
try this link maybe:
https://mega.nz/#!f5pXVAIZ!nWmaFU9d5ux6FOUI6Kdv3GK8RObswoZzxRwpQVEvpxo

There's an easy way to get Root on 5.1.1 without having to downgrade back to kitkat
- Unlock your bootloader on Sony's Website
- Search for a custom kernel here that is for 5.1.1 ( e.g. Androplus, etc )
- Boot into fastboot mode in Flashtool and flash the kernel
- You now get recovery because the kernel comes with a custom recovery
- Flash SuperSu's latest Zip file to get root
- Enjoy

Maybe be careful when recommending that without mentioning, that he would loose his DRM keys in that process... so I would always add the comment, that he should have a backup before unlocking. Or at least mention the loss of the DRM keys as a warning.

[GUIDE]How to Revert to Stock/Reflash firmware/Unroot[TWRP/NON-TWRP]

Hey Xda,
Today I present you a guide on how to
REVERT TO STOCK OR REFLASH​ firmware on the Asus Zenfone 2 Laser ZE5550KL.
This guide is applicable to both types of users ie who use TWRP and who don't use TWRP.After following this guide your phone will also be unrooted.
For TWRP Users
Here I give you links to two firmwares which you can directly flash via TWRP recovery.
Version:1.13.40.496
Link
Version:1.17.40.1234
Link
For Stock/Non-TWRP Users
The procedure is a little long here ==>
1. Download the official firmware from asus website.
2. Copy the firmware to the Micro-SD and rename the file (firmware) by one more(version).This renaming should be according to your current firmware version.If you have 17.something firmware and you download 16.something firmware then rename the 16.x.x file to some thing like 17.x.x For eg. if you have 1.17.40.763 then rename 16.x.x file to 1.17.40.764.
3. Reboot the phone.Android should automatically find the update file and offer to automatically update the software.Do it !!
4. Go to stock Recovery and wipe cache , dalvik cache and data.
5. Reboot device. Your phone will now be unrooted(if it was rooted before).
DONT FORGET TO PRESS THE THANKS BUTTON IF I HELPED YOU.

Before going back to stock and re-rooting to see if the issue was still present, I thought I'd ask if this is something to worry about ? I have the ZE551KL (Z00T) and have been flashing for this device with no problems whatsoever. What is it that I did while unlocking , rooting, and flashing twrp that may explain why the build number and device model don't match? Additionally, at times my PC will recognize my device as a MotoG when my device is connected to the PC via USB . I don't have access to my PC right now so I can't say this with certainty, but I think my PC recognises my device as a MotoG only when the device is in TWRP.. Maybe that means something was done wrong while unlocking the bootloader?

Well, I'll be damned. I was doing so much flashing at the time that I didn't put it together. Oh well. I've been back on the stock CM kernel for days and everything finally works as it should again.

Will flashing this stock ROM on TWRP replace my current TWRP recovery to stock recovery on boot?

Correct stock file for Indian Version LLD-AL10

I downloaded and tried flashing this one but got an error at 5%.
LLD-AL00C00B172 (8.0.0.172),LLD-TL10C00B172 (8.0.0.172),LLD-AL10C00B172 (8.0.0.172)
Can someone tell me which version i correct for me?

Does it match your device model? Also what was the last firmware you had on the device?
Sent from my LLD-L31 using Tapatalk

I don't remember the last firmware but the device is LLD-AL10
I file I tried was the latest I could find on the website. I just tried another file, got the same error.

Your device might be a LLD-AL10 however the last 4 digits is important.
For example you have :-
LLD-AL10C00B172
LLD-AL10C01B171
The C bit is the important bit. Also make sure you download the FullOTA-MF file set.

Not sure as my phone hasn't been unlocked or twrp'd. However if its like the LLD-L31C432 then your best bet might be to try LLD-AL10C00B163 as on mine i can't install LLD-L31C432B132 however i was able to install LLD-L31C432B130 or LLD-L31C432B131.

Holy ****! this worked with HuR tool. But the only problem is, its a chinese ROM, without play store. If you tell me what those 3 files were, i'll download the Indian version and flash it. Thanks a lot though

From what i understand its the following
1) Format an SDcard and Create a folder called dload in the sdcard.
2) Extract the contents of update.zip to the dload folder.
3) Place the SDCard in the phone.
4) Press and Hold VOL up VOL Down then the power button.

Not Receiving OTA UPDATES!!!!

Hi all,
Please help me out!
I have a note 8 with (N950U) - XAA/XAA/SPR - and I have not received a single OTA update!
I used the firmware science method to install a few updates and flashed (using Odin) when Oreo was released.
But now I want to solve this issue and start receiving OTA updates. I do not mind using Odin again to get this sorted - but preferable not lose my data.
Thank you

You have a branded device but not linked with any carrier in US. Change your firmware to an unbranded one and from CRL2 you will receive the last oreo stable CSA1 or you can download the firmware directly from an app like Updato from Google Play and wait that a beta stable on pie will be released.

Ok, this is the first guide as reference:

Odin Tool normal just in case you need it:
https://androidfilehost.com/?fid=818070582850505662
I used the patched version:
https://androidfilehost.com/?fid=890129502657595813
Last Oreo Odin rom available:
https://androidfilehost.com/?fid=1395089523397886161
Staying in this version you have to theoretically receive updates from OTA

Thank you i am going to try this.
Question, the guide says "Note - If you are flashing Unlocked Firmware from Carrier Firmware you must use Prince Comsy Odin otherwise, use regular Odin."
So, in my case i am going from a 950U firmware to 950U1, should i use odin or prince comsy odin? and is there a way to keep my data? or will it be reset for sure?

Use the modded Odin mentioned.
You can keep your data but in this case you will go to switch to a different firmware so is better that you do a backup with SmartSwitch and them go to recovery, do a format/factory reset , then in Odin flash the firmware, reboot and restore your data

Great I will do a full reset. But when you say modded Odin is the prince comsey Odin?

try restoring your phone's firmware using Samsung Smart Switch.

I'm not sure what exactly is Comsy, I read about it but I guess this was an older version, I used the patched version linked in one of my previous posts and works like a charm. I switch from N950U to N950U1 and I had any trouble doing this procedure. About keep your data if you use Home_CSC you will preserve it but you need to delete your old CSC that is where go the preferences of a carrier, so you have to use CSC_oyn file instead

If you are not using a Sprint sim and your device is not a locked carrier (under contract) this message can't appear.
If you follow all the steps, factory resetting first in recovery, then flashing the CRL2 firmware including CSC_oyn then the bloat from the carrier has to be deleted.
It's probably too that you backed up settings with Smart Switch and then restored it, if this is the case try by factory resetting again and restore your backup but not your settings, also check any app related with sim provider that you backed up avoiding restore it.

Need help please

Hi, like Ahmed I also have a SM-N950U XAA/XAA/SPR. My note 8 is not receiving OTA update and it seems like it never will (writing on 01-Apr-2019). Its probably because im using it in Pakistan. Im fairly new to the OTA and manual OS flashing thing. I dont understand any CRL2 or 3 whatever it is.. I would really appreciate if i could get a step by step guide about how to do it since im going to be making a transition from Nougat to Oreo (Or pie of possible). Please please i would really appreciate your help. as i dont want to brick my phone and i dont know what to do.
Thanks a bunch.

Well, the steps are in all the thread.
Let´s go for the obvious first; I guess actually you are not using a sim card from US so you are out of US now and then no need on any carrier´s bloat.
You need first of all switch to an unbranded firmware, it´s mean from N950U to N950U1.
If you are actually on nougat then flash this firmware that is the latest Oreo since you can upgrade after to Pie https://androidfilehost.com/?fid=1395089523397886161 Use this modded Odin to flash it https://androidfilehost.com/?fid=890129502657595813
Process to flash through Odin and switch correctly to unbranded firmware:
- First of all backup your important data using SmartSwitch (you can do it on a SDCard inside your device)
- Enable USB Debugging in developer options and OEM unlock if present.
- Go to recovery and Factory Reset/Format Data.
- Then use menu "Reboot to bootloader" to go to download mode.
- Load the files on Odin and from the two CSC choose CSC_OYN to delete/reset all the preferences, start flashing and wait PASS message.
- Reboot normally to system.
From here to upgrade to Pie go to this site https://firmware.science and complete the following: Model number: SM-N950U1 (this will be from now your model number), in Current version put the firmware ended with CRL2 (the firmware that you flashed previously) and download the first Beta ended on CSAB; move the zip onto your device and go to recovery and flash it using Update from sdcard (this could be wipe again your data).
If you want to update to the second Beta repeat the previous process; complete as Current version: firmware ended on CSAB and choose and download firmware ended on CSBB (less sized).
And finally to go to the last Beta available do the same, Current version; firmware ended on CSBB and download firmware ended on ZSC2 and flash it again using recovery updater.
It could be more Betas but not available yet on Firmware.science.
From beta firmware it´s unlikely that you receive OTA but when an Official Pie be release theoretically you have to receive them normally or if you want to receive them just now then you have to stay on Oreo CRL2 you´ll receive an Oreo OTA update CSA1 (more or less 40MB) and wait from there that an official Pie will be release.

First of all thanks a lot for getting back to me so quick i really appreciate it. Yes youre right about not using the US sim card. If you could just bare with my rookie questions a bit more.
Do i download the "firmware" and modded odin into my note 08 by following your shared links or do i have to download them into PC. If phone, then shud it be on SD card or internal storage?
Second, """Go to recovery and Factory Reset/Format Data.

I only know how to enable developer mode. Thats when you tap built number. But debugger and OEM idk that. And everything you mentioned in """ how do i do it ? Whats to be done on PC and what on computer i have no clue. Youll have to guide me like a child about this i apologise.
Judging by your pie statements. Thats very techincal to do. So i believe its better off going for Oreo for now and wait for the Pie update automatically.
Thanks in advance

The first firmware linked at Android File Host is Oreo, this firmware you have to flash it using Odin so download it with your pc and put it in any place of your preference onto your pc DON´T move it to your device.
Second, """Go to recovery and Factory Reset/Format Data.

This is indicated to make a clean flash, to delete/reset some APN preferences and some traces that came preinstalled with this device linked to a carrier.
- Then use menu "Reboot to bootloader" to go to download mode.
- Load the files on Odin and from the two CSC choose CSC_OYN to delete/reset all the preferences, start flashing and wait PASS message.

Unzip the firmware that you downloaded till get some files in .tar format, within these files you´ll find two CSC files, choose the CSC_OYN file and not the CSC_HOME on the CSC box and all the other files load them on every corresponding box: BL, AP, CP that you´ll find in Odin.
I only know how to enable developer mode. Thats when you tap built number. But debugger and OEM idk that. And everything you mentioned in """ how do i do it ? Whats to be done on PC and what on computer i have no clue. Youll have to guide me like a child about this i apologise.

No, I refer to OEM unlock option but I forgot that this option is not visible in this variant so forget it, just enable Developer Options and USB Debugging that you will find them then to tap on build number 7 times.
Here´s a tutorial about how to use Odin https://androidmtk.com/flash-samsung-stock-rom-using-odin just replace some step by the indicated here.
Judging by your pie statements. Thats very techincal to do. So i believe its better off going for Oreo for now and wait for the Pie update automatically.

Really is not so hard to do all this but if you´re not so familiar you can flash just the firmware linked and wait for an OTA prompt update.

[Q] After rooting my wifi is not working anymore someone help me

After rooting my phone the wifi is not working anymore no matyyhow i clock wifi on its keep turning off i try to reset factory data nothing change pleaseeeeeee guys help me

Hi,
First thing I'd do is to reset it to it's original state and thus unroot it.
Does that bring Wi-Fi back ?
Then I would re-root to se if that turns Wi-Fi off again.
If so , then it seems the unrooting has problem somewhere... I think I've seen that it implies playing with a modded kernel image or something like that. So it can easily cause problems.
If not then you probably unrooted it the wrong way first time.
Regards.

I had the same problem, fixed it by flashing the same boot.img that belongs to my os version (cn red magic 2.14).

Look up your build number in settings, mine is 2.14 as you can see in the screenshot.
Download the appropiate version you need from http://ui.nubia.cn/rom/detail/62
If you also have the China rom ofc.
Follow the root steps in the other screenshot.

Hi,
So if I get you right : I download the ROM for the Global version.
Once done I extract the boot.img and patch it with Magisk Manager.
And then I flash the patched file and it should be good ?
I'm going to try this right now
UPDATE : done. It works indeed

Hi,
Can you please tell me what version of the firmaware you're running ?
I think there are three of those :
- China
- North America
- Europe
To know which one you are running, just go to settings and at the very bottom "About this phone".
And there, at the very bottom, the version of the ROM used.
Without that info, I won't be able to provide the needed patched boot image.
I assume your bootloader is unlocked and you DID NOT install TWRP.
Regards.

Hi,
Yes, CN stands for China.
So you have Chinese 2.14 version.
I'll see if I can find that boot.img you need.
Please note : I will return the device vbecause of it's really BAD software.
So I will not be able to help any longer after this
Regards.
